Answer:
6/7 ≈ 85.7%
Step-by-step explanation:
The probability that a 0 was transmitted and received is 0.5·0.9 = 0.45.
The probability that a 1 was transmitted and a 0 received is 0.5·0.15 = 0.075.
Then the probability that a 0 was received is 0.45 +0.075 = 0.525.
The probability of interest is ...
p(0 transmitted | 0 received) = p(0 transmitted & received)/p(0 received)
= 0.45/0.525 = 6/7 ≈ 85.7%
Answer:
y=6.75x
Step-by-step explanation:
he xharges 6.75 per hour, so 6.75x equals the total price, y

Answer: 4/5
Step-by-step explanation:
--------------------------------No of vehicles involved
Did alcohol play a role - - 1 - - - - - 2 - - - - - 3
Yes---------------------------- 60 - - - - 110 - - - 30=200
No - - - - - - - - - - - - - - - - 40 - -- - 215 - - - 45 =300
- - - - - - - - - - - - - - - - - - 100 - - - - 325 - - - 75
What proportion of accidents involved more than one vehicle;
Total accident = (100 + 325 + 75) = 500
Number of accidents involving more than one vehicle = (accident involving 2 vehicles + accident involving 3 vehicles)
(325 + 75) = 400
Therefore, proportion of accidents involved more than one vehicle = (Accident involving more than one vehicle / total accidents)
= (400/ 500) = 4/5
